I'm up to a little over 60 kilometres worth of biking on my new bike, and so far I'm really enjoying getting outside again. The first few rides I did were pretty painful, both from a muscle perspective and also from a cardio perspective. But I'm up to about 16 kilometres a ride now, and I can see myself doing a 25 kilometre ride fairly soon as well. I've actually been using the RunKeeper application on my iPhone to track my progress. It's a free application as well as a free service (there's a paid upgrade option). I don't think I'll upgrade, mainly because I don't think I'd need any of the perks ...
